An example screenshot of an "Oops! Uploaded bytes exceed file size" error message.

There are different versions of the error including:

  • Oops! Upload Failed
  • Oops! Uploaded bytes exceed file size
  • Oops! Internal database error
  • Oops! Failed to match expected file size

Affects

Users may see this error when attempting to upload media via Kaltura MediaSpace or the Kaltura Canvas integration. The errors seem to be more common with larger files over 1.5 GB in size and when uploading via fast connections.

Workarounds

Try uploading your file again

Retrying your upload may result in a successful upload. Users can also try uploading from another internet connection or exporting, publishing, or compressing it to a smaller size (for example choosing 720p - 1280 x 720 frame size - in Powerpoint, Camtasia, or other software) before uploading. Users may also consider splitting up their video into smaller segments and uploading the smaller segments.

Even when Kaltura MediaSpace is running smoothly other internet service providers may experience slower service which could limit your upload speed. Test your speed by going to speedtest.net, and click Go to run the test. Upload speeds and Kaltura's upload performance varies, but an upload speed of 10 Mbps should be able to upload a 250 MB file to Kaltura in about 4.5 minutes.
